Heat pump dryer is use of reverse Carnot principle .With free air to absorb heat and transfer it to the drying chamber, drying room temperature to achieve improved, with the appropriate humidity and dehumidification equipment to achieve dry materials. Heat pump dryer Compressor - heat exchangers - Chokes - heat sink (outside the machine) - Compressor and other devices constitute a refrigerant cycle system. Under the action of the compressor in the refrigerant circulating in the system flow, it is done in the gaseous booster compressor heating process (temperature up to 100 ℃), releasing it into the machine dry in room temperature air heated by the heat, while they have been and converted to liquid cooling flow, when it runs out machines, liquid absorbs heat quickly evaporates once again transformed into a gaseous state, while the temperature dropped to minus 20℃-30℃, then the air around the heat sink will continuously transferring heat to the refrigerant. Refrigerant continuous cycle to achieve the heat in the air transport to the drying room heating room air temperature to achieve the purpose of dry material. LD HEAT PUMP DRYER Working principle:
